DUMPINGfVEHICLE.v

SPECIFICATION forming par-t of Letters Patent No. 771,936, daten october 1 1, 1904.

Application filed November 18, 1903. Serial No 181,576. (No model.)

To fI/Z/ whom, t rma/,y concern:

Beit known that I, ROBERT B. RIFENBERIOK, a citizen of the United States, and a resident of Cleveland. county of Cuyahoga, and State of Chio, have invented a new and useful Improvementin Dumping-Vehicles, of whichv the following is a specification, the principle of the invention being herein explained and the best mode in which 1 have contemplated applying that principle, so as to distinguish it from other inventions..

My invention relates to dumping-vehicles, its object being to provide means whereby vehicles of the character may be used with greater facility and economy of operation than has heretofore, in sovfar as I am aware, been obtained.

Said invention consists of means hereinafter fully described,andparticularly set forth in the claims.

The annexed drawingsand the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various Inechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure 1 represents a side elevation of a d umping-vehicle embodying my invention, the wheels being shown diagrammatically and a tilted position of the body being shown in dotted lines. Fig. 2 represents, upon a scale larger than that of Fig. 1, a rear end view of the vehicle-body, a portion of the rear door being broken away to disclose the interior of said body, a part being shown in vertical section.

Asuitable frameA is provided and mounted upon springs B in the usual manner, said springs being in turn supported upon the vehicles axles, as will be readily understood. Upon the rear portion of the side members t t of such frame are bolted, respectively, two trunnion-bearings t I, Fig. 2.

To the sides of the body C are secured two trunnions c c, which are respectively mounted in the bearings b The front of the body is provided with a hasp c', which engages a staple b2, secured upon the frame, and is secured thereon by means of a pin b3. When so secured, the body is held in its normal position, in which its top is substantially pary allel with the frame. The body consists generically of two partsviz., the main body portion, including its front, sides, and -bottom and attached parts, and the .rearl door. The bottom of the body inclinesdownwardly from the front to the rear, as shown, whereby it is seen that it is necessary to cause the body to rotate through a comparatively small arc in order to impartto it a position such as will bring the bottom thereof into a position substantially perpendicular, as shown in dotted lines in Fig. 1, and thereby insure the discharge of all of the contents of the vehicle. The trunnions arelplaced so as to cause the vertical plane passing through their axes to fall forward of the center of gravity of the body when filled with material, so that only a slight lift at the front will be necessary to depress the rear end, as will be readily understood. y Substantially parallel with the bottomdplate of the body and some distance above 'it is a perforated plate c2, forming a liquid-contain+ ing water-tight chamber c3, the rear end being closed by means of an upright wall or plate c4, Fig. 2. The rear of the bottom plate of the body is tapped by a drain-cock 05, by means of which liquid in such chamber c3 may be withdrawn. This chamber is constructed and used only when the vehicle isused to haul wet substances, such as garbage, the perforations allowing water or other liquid to drain through into the chamber, and so become separated from the solid matter, as will be understood.

The rear end of the body is closed by means of a door D, which is made water-tight by means of a suitable gasket when the vehicle is used for hauling garbage. Upon the upper part of the rear end of the body are secured two curved guides c6 c, each provided with a guiding-slot c7, Fig. 1. The lower ends of these slots terminate in the vicinity of the upper end of thebody, as shown, and are respectively engaged by trunnions Z d, formed by a rod projecting laterally from the upper end of the door. It will hence be seen that the door may oscillate about the axis of such trunnions. Pivoted to the sides of the door,

TOO

' end oi' hangers cv d',

respectively, are two links E E, whose lower ends are journaled upon removable pins e e, respectively. These pins are seated in the which are fixed to the side members a a, as shown. The construction is hence such as to cause the said door to be closed tightly when the body is in its normal position and to open automatically when the body is tilted, such tilting causing the trunnions 0l to run up the guiding-slots c7, oscillating the links E E, and thus throwing the lower end of the door outwardly, at the same time causing4 it to travel downward a distance less than that of the travel of the end of the body itself. The door is hence practically removed from the path of the discharged contents during their transit and at the same time prevented from coming into contact with the ground, as is shown.

A suitable stop is provided for limiting the downward-tiltingmovementof thebody. For this purpose the rear axle b* is preferably ropped between the wheel-hubs, as shown in The pivot-pins e e are provided with heads and are secured in place by means of Cotterpins e' e', which may be removed. When it is desired to open the door without tilting the body, these lpins are removed and the links permitted to swing free.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a dumping-vehicle,- the combination ot' a suitable frame, atiltable body mounted upon such frame, said body including a rear door and guides therefor; and connections with said frame, whereby said door is caused to open when the body is tilted.

2. In adumping-vehicle, the combination of a suitable frame, a tiltable vehicle body mounted thereon, a door for closing the end of the latter, means connected to said door and adapted to travel upon said body, and pivotal connections between said door and said frame constructed to cause such door to travel in planes diiferent relatively to such vehicle-body, when the latter is tilted.

3. In a dumping-vehicle, the combination of a tiltable vehicle-body, a door for closing the end thereof, and means constructed to cause such door to travel upon the body end a distance lessthan the distance of travel of said body end, when said vehicle-body is tilted.

4. In adumping-vehicle, the combination of a tiltable vehicle-body, a door for closing the end thereof and movably mounted thereon, and means for causing such door to travel upon the body end a less distance than the distance of travel of said body end, when the vehiclebody is tilted.

5. In a dumping-vehicle, the combination of a tiltable vehicle-body, a door for closing the end thereof and movably mounted thereon, and means for causing such door to open outwardly from, and to cause it to travel upon the body end a less distance downwardly than, such body end, when the vehicle-body is tilted downwardly.

6. In adumping-vehicle, the combination of a suitable frame, a tiltable body mounted thereon, said body including a main portion, guides mounted upon such main portion, and a rear door engaging such guides; and connections between said door and frame, whereby said door is caused to open when the body is tilted.

7. In adumping-vehicle, the combination of a suitable frame, a tiltable body mounted thereon, said body including a main portion, guides mounted upon such portion and a rear door provided with trunnions engaging said guides; and pivotal links each having an axis of oscillation fixed relatively to said frame, said links being connected with said door.

8. In a dumping-vehicle, the combination of a tiltable vehicle-body provided with a bottom inclining downwardly from front to rear when said body is in a normal position; aliquid-receiving chamber at such bottom, such chamber having a perforated top and provided with a drain-cock for removing liquid therefrom; a door for closing the end of said vehicle-body and movably mounted thereon; and means constructed to cause such door to travel in planes different relatively to said Vehicle-body when the latter is tilted.

Signed by me this 30th day of October, 1908.
